/**
 * Service Description: Manages Products and ProductSets of reference images for use in product
 * search. It uses the following resource model:
 *
 * - The API has a collection of [ProductSet][google.cloud.vision.v1.ProductSet]
 * resources, named `projects/&#42;/locations/&#42;/productSets/*`, which acts as a way
 * to put different products into groups to limit identification.
 *
 * In parallel,
 *
 * - The API has a collection of [Product][google.cloud.vision.v1.Product]
 * resources, named
 * `projects/&#42;/locations/&#42;/products/*`
 *
 * - Each [Product][google.cloud.vision.v1.Product] has a collection of
 * [ReferenceImage][google.cloud.vision.v1.ReferenceImage] resources, named
 * `projects/&#42;/locations/&#42;/products/&#42;/referenceImages/*`
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods.
 *
 * Many parameters require resource names to be formatted in a particular way. To
 * assist with these names, this class includes a format method for each type of
 * name, and additionally a parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.
